My X.org crashes (the "screen frozen, but mouse pointer moves" bug) within a few seconds of starting X with these drivers, instead of a few days with the previous drivers (at least when using RenderAccel).

For what it's worth, I'm using a two monitors, each connected to a separate card; with the cards in my machine being "GeForce4 MX 440" (AGP) and "GeForce2 MX/MX 400" (PCI). There's nothing particularly special about my X config file (and I'm running Linux 2.6.11 on an x64_86 machine).

Should I just buy a new graphics card to avoid the "screen frozen, but mouse pointer moves" bug?
